These are all Order of Battle sheets for playing games by postal mail. Creators took a variety of approaches to creating the sheets, so some games have a single sheet for both sides in the game, while others have multiple sheets.
In general, because the sheets are in a wide variety of file formats, you have to click twice to download the sheet, once on the number after the title of the game, and a second time on the page corresponding to the sheet to cause the sheet to download.
